"We are here today in Grant Park to show the city, 'No, we are done with these borders. We are done with the division. We know who our targets are. We know how things are operating, and we are going to organize our neighborhoods, as you see here, and it's only going to get bigger from here on out," said Crystal Vance-Guerra of Occupy El Barrio.

Members of the Occupy movement are fighting against what they say is an imbalace in social and economic equality and the undue influence of big business on government. Occupy Chicago has aligned itself with another group, the Coalition Against NATO/G8, which plans protests in advance and in concert with the upcoming summit of NATO leaders, who they say "meet on behalf of the 1% of the world, the rich and the powerful, the bankers and generals."
